To all whom, it may concern.-

Beit known that I, OLIVER G. LAW, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful. Improvements in Book-Supports and Arm- Rests; and I do declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and usefulimprovements in combined adjustable .booksupports. The device is especially adapted for large andheavybookssuch, for example, as are used in recorders offices.

The object of the invention is to provide a device of this character by means of which the book may be easily and quickly adjusted to the necessary positions and by means of which the arm may be supported in an easy and natural position to enable the bookkeeper or other person to inake the entries therein without fatiguing the arm or the back when writing at the bottom of a page.

Preceding a detail description of my invention, reference is made to the accompanying drawings, of which- 7 Figure 1 is a perspective view of my improved combined book-support and arm-rest, showing a book thereon. Fig. 2 is a rear perspective view with the book removed, showing the desk elevated by the adjusting devices.- Fig. 3 is a detail view of the adjusting mechanism for elevating the desk.

Throughout the specification similar letters suitable height permitted by the length of the ratchets D. I have provided additional means forsupporting the desk B in a still higher position should it be necessary. These means consist of a tube F, having a longitudinal slot F therein. This tube is secured to the base-board A by means of a staple or other suitable device F. scopic rod in said tube, which may be elevated orlowered therein by means of a thumbscrew F, the outer end of said rod coming in contact with the under side of the desk. It will thereforebe seen that the desk B may be supported in higher positions than the means provided by the ratchets D and E.

V G designates adjustable sides,each of which has inclined slots G therein through which projectstuds or pins G, said studs or pins being secured to the sides of the desk B and providing guides which direct the movements of the sides G and which also support said sides in any'position in which they may be moved. The upper edges of the sides G have inclinations which coincide with the upper surface of the desk B. As shown in Fig. 1, one of the sides is elevated-to a position above the surface of the table B and is supporting one side of the book H. Each of said sides G has a fingerpiece I, by means of which the sides are moved to any desired position. As shown in Fig. 2, the sides are in their lower position, the upper edges thereof coinciding with the plane of the upper surface of the desk.

It will be observed that there are a variety F is a teleof adjustments obtainable by means herein the side pieces G by means of which the slop-v ing side of the book may be brought to a level position corresponding to the opposite side.

IOO

As shown in Fig. 1, an arm-rest is in a position on an incline which coincides with the upper surface of the book. This position is enabled by placing the ends M of the ratchetbar M in the desired notches in the ratchets K, and there is thereby provided a rest which supports the arm in an easy and natural position.

Having described my invention, 1 claim A book rest or support comprising a baseboard A, a desk having a hinged connection to the front end of said base-board, adjustable side pieces on said desk, the side pieces being of substantially triangular shape and having two inclined slots therein,pins projecting from the stationary sides of the desk and entering OLIVER G. LAW.
